It sure can be a sick joke but if a person has the time and inclination to study market maker maneuvers, he can either follow along with them or exploit them for decent daily gains. I have watched this stock every day on level 2, all day, for over a year now and I've gotten to where I can see up and down moves (especially down ones) coming well before they happen by the positions of the various market makers.
I always feel sorry for daytraders who jump into this stock, long or short, because of news, or it's on the percentage gainer or loser list. They almost always end up bailing at a loss. The market makers really control this stock, although it's been getting away from them a little more lately :)
